Answer:
The specific heat of the metal is 0.451 J/g°C (This could be iron).
Explanation:
<u>Step 1:</u> Data given
Mass of the unknown metal = 217 grams
The metal absorbs 1.43 kJ of heat
The temperature increases from 24.5°C to 39.1 °C
<u>Step 2:</u> Calculate the specific heat of the metal
q = m*c*ΔT
⇒ q = the heat transfer = 1.43 kJ
⇒ m = the mass of the unknown metal = 217 grams
⇒ c = the specific heat of the metal = TO BE DETERMINED
⇒ ΔT = the change of temperature = T2 - T1 = 39.1 - 24.5 = 14.6 °C
q = 1430 J = 217g * C * 14.6 °C
C = 0.451 J/ g°C
The specific heat of the metal is 0.451 J/g°C (This could be iron).
